Notes on the cars:
- Brabham BT35  (Mike Hansen): New to Mike Hansen (Belmont, CA) and Steve Marx (Fremont, CA) of Hansen-Marx Racing (or Marx-Hansen Racing) and raced by them in SCCA Regionals and Nationals predominately in southern California in 1971. Retained by the pair for 1972, and raced by Hansen in SCCA Nationals up and down the west coast, and then in Pro events later in the season. To Bill Cooper (San Jose, CA) for 1973, and used in SCCA Regionals. Retained by Cooper for 1974 and raced in SCCA Nationals. Seen less often in 1975, and advertised by Cooper with a BDA engine from September 1975 to July 1976. It is reported to have gone to Tom Smith after Cooper. It was bought from Tommy Smith in July 1978 by John Hafkenschiel and raced in Californian Formula Atlantic before selling it in the winter of 1984. In November 2016, Ron Hornig (Laramie, Wyoming) bought the car and has thoroughly restored it. Note that Hornig also has two F3 BT35s which he uses in historic racing.
- Brabham BT29  (Thomas E. Kornell): Sold new to Tom Kornell (Seal Beach, CA) and raced in SCCA Divisional and Pro Formula B in 1971 and 1972. Kornell added a sports car nose and a more substantial rollhoop amongst other changes. He ordered a Brabham BT41 for 1973 and the BT29 went to Fred Opert as a trade. Subsequent history unknown.
- Brabham BT29  (Larry Wright): This late BT29 remained unused in 1970 and was sold by Charlie Hayes to Larry Wright (Riverside, CA) in Dec 1970, taking Wright's Chevron B15 in part exchange. Wright raced the orange-and-yellow #83 Brabham in Pro events and in SCCA National and Regional events on the west coast. In June 1973, he wrecked the car in practice for a National at Laguna Seca and replaced it with the ex-Archie Snider BT29. The damaged chassis went to Marc Bahner in 1974 who eventually repaired it and sold it to Lou Pavesi in 1980. It later passed to Steve Pike in Australia in 1993 and then to Jim McConville in 1998.
- Lola T240 [HU4] (Syd Demovsky): New to Syd Demovsky (Chicago, IL) and his red #11 Demovsky Racing Lola T240 in the 1971 Pro FB series. Retained for 1972 and again did a full season, still red and still using #11. In June 1973 it was sold together with HU5 by Charlie Hayes to Eric Steele of Formula Cars Inc (Mansfield, Ohio). It is believed that the two cars were intended for the Mid-Ohio Racing School. Subsequent history unknown. A car with this chassis number raced by Bob Juggins in 1996/97.
- Brabham BT29  (Phil Palm): This is one of a pair of late BT29s acquired by California dealer Charlie Hayes which remained unraced during 1970. It was sold it March 1971 to Doug Brenner (Pasadena, CA) and raced in Pro events and in SCCA Nationals that season. Brenner raced the yellow Brabham in the two Bogotá races in early 1972 and then sold it to Phil Palm and Ron Pohl 1972 who retained Brenner's entry number of #26 and raced the car in 1972. They sold it to Bill Summers (Middleton, WI) who raced it in SCCA Regional and Midwest Council races at Elkhart Lake, Brainerd, and Blackhawk Farms, and advertised it in October 1978 with a CRW engine. The next owner was Bob Mijolevic (Pardeeville, WI) who used it in Midwest Council events in 1980, later fitting a Mazda engine for use in autocross. Mijolevic last raced the car in September 1982 but after that the history is largely unknown until it was bought by Cy Moreland (Trainer, PA) who in turn sold it to Dave Burch (Los Altos, CA). Rebuilt in the mid-1990s using a replacement Marc Bahner chassis. Sold in late 2011 to Wayne Wilson (Sydney, NSW, Australia).
- Brabham BT21A  (John R Coolick): New to Dave Webster (Newport Beach, CA) for Formula B in 1967, finishing second in SPDiv division. To Joe Alves (Sherman Oaks, CA), who raced it from the start of 1968 to mid-1969, finishing fourth in SoPac FB in 1968 and fifth in 1969. Then to John Coolick (Wilmington, CA) who raced it in local Formula B, generally at Riverside, from 1970 to 1975. Advertised by Coolick with a big valve twin cam engine in October 1975. Subsequently to Eric Stromwall 1977, then Todd Bishop 1979, and then John Dixon 1989. Bought by Tim Kuchel (Adelaide, Australia) in early 2006, then sold to Frank Arronis (Sydney, Australia) in 2020.
- March 722  (Dick Doherty): New to Dick Doherty (Hollywood, CA) and raced in Pro FB in 1972, as well as Cal Club SCCA events. Retained for Cal Club events in 1973, 1974 and 1975. Rebuilt by Wilbur Bunce to 75B specification for 1976, and run by him in Californian SCCA races for Dennis Firestone to drive, and later in Pro Formula Atlantic races in California for Ron Dykes, Rocky Moran, and Bob Lazier. It was red, and wore #10, #70 and #87 during the season. Sold to Ted Titmas (Van Nuys, CA) in early 1977, and run by him as a hire car in 1977, but Titmas had two cars in 1977, one red and one orange, and it is unclear which was which. Subsequent history unknown.
- Brabham BT29 (Bob Criss): In 1972, Stephen M. Cole (Orange, CA) entered a Brabham BT29 in Pro Formula B races for Bob Criss (originally from Terre Haute, IN, but by 1972 of Newport Beach, CA). The car was blue and wore #64 when raced by Criss. Cole himself also raced in Nationals and is thought to have been racing the same car at Riverside in May 1972. Criss signed with Mary & Tom Page's Page Racing for Indy racing in 1973 but was killed in a testing session in April 1973. Criss was Robert Dale Criss, born 1938, and should not be confused with the Bob Criss from Bethel Park, PA, who drove an Austin-Healey Sprite in SCCA racing as a member of Steel Cities Region at about this time. According to Richard vPaul, Cole sold the Brabham via Chuck Willis to Jeff Alkana (Azusa, CA), who registered it with CSCC in July 1974, and went on to race it in the Formula B class in southern California from July 1974 to March 1975. The car was given as chassis BT29-16, but had been rebuilt on a new frame "WM74" fabricated by Wayne Mitchell. The car passed to William Nair in 1975, then at some later date from Nair to Terry Peterson, this sale being brokered by Wayne Mitchell. The car was acquired from Peterson by Peter McGlone in 1991, and remained with him until sold to Mark Shillingburg in 2018.
- Brabham BT29 (Charles R "Chuck" McCain): Charles R "Chuck" McCain (Tucson, AZ) raced a Brabham BT29 in the IMSA Pro Formula B race at Las Vegas International Speedrome in July 1972, and in Arizona Sports Racing Association (ASRA) events at Phoenix International Raceway and Mel Larson's Phoenix Dragway in 1973 and early 1974. He advertised the car, together with his Chevron B17b, in March 1974. This car may have been chassis BT29-21, later owned by Jaime Chamberlain in Arizona.
- Lola T240 (Bill Middleton): Bill Middleton (Newport Beach, CA) bought a yellow #31 Lola T240 late in the 1971 Southern Pacific FB season to replace an elderly Brabham BT21C. He won enough points in this car to clinch second place in the division. Retained for 1972 and used in both Pro and SPDiv events, winning the division by a considerable margin. Last seen in late July 1972, after which Middleton acquired a Brabham BT38B. Advertised by Fred Opert in October 1972 and again in February 1973, implying it had gone to Opert in part-exchange when Middleton bought the Brabham. Subsequent history unknown.
- March 722 (Olney "Bill" Mairs): Olney "Bill" Mairs (originally from New York but resident in Malibu, CA at this time) raced an orange #12 March 722 in three Pro races during the 1972 season. In 1973, he raced the car in SCCA Nationals and Regionals in California in the early part of the year, but later that season he raced in SCCA Nationals at Pocono and Bryar. Subsequent history unknown.
The identification of individual cars in these results is based on the material presented elsewhere in this site and may in some cases contradict the organisers' original results.
1970 US FB results were compiled from Autoweek reports by Jim Thurman; 1971 results were transcribed from Autoweek by Allen Brown and 1972 results were compiled by Chris Townsend from an SCCA results publication.
The US Formula B series did not continue in 1973 but a race was organised in Caracas in March 1973 that fits here probably better than anywhere else, as do the occasional SCCA F/Atlantic and FB races in 1974 and 1975.
